Abstract : In order to forecast the refractivity structure in the atmosphere, the accompanying temperature and moisture structures must be forecast. As a means of providing shipboard-generated forecasts of low-level temperature and moisture structures in the planetary boundary layer, the Navy has converted a sophisticated, turbulence model to a microcomputer. This model, called the Navy Over-Water Local Atmospheric Prediction System (NOWLAPS), is part of the Tactical Environmental Support System (TESS), a shipboard, automated, environmental diagnosis/prediction system. NOWLAPS is a one-dimensional, second order closure model that can provide forecasts over water for temperature, moisture, and winds up to heights of 2 km., and out to 24 hrs. From these temperature and moisture distributions, the refractivity profile can be generated.
